Product description The 3:1, 4:1 double-walled pipe is composed of double-layer halogen-free flame-retardant polyolefin and hot melt adhesive. The outer polyolefin is made of insulating, halogen-free and flame-retardant material. The inner layer of hot melt adhesive can buffer mechanical strain and seal strong. The main functions are sealing, waterproof, anti-corrosion, anti-leakage, multi-strand wiring harness and insulation. It is mainly used in various wiring harnesses, marine wires and metal pipes that need to be sealed, insulated, bundled and fixed. Features The outer layer is flame-retardant, anti-ultraviolet, and wear-resistant Shrink ratio 3:1 Environmental protection standard RoHS REACH Color: black, orange, red, yellow, transparent, other colors can be customized
